结构中的Objective-C对象的替代方案(ARC) [英] Alternative to Objective-C objects in structs (ARC)

问题描述

我这里有以下代码，因为它在结构中结合了Objective-C对象，因此无法在ARC上运行:

I have the following code here that won't run on ARC since it combines Objective-C objects in structs:

struct SingleToManyRelation {
    id singleObject;
    NSSet* manyObjects;
}

我知道这让人想起Core Data，但这不是重点；)我只是在寻找一种解决方案来实现类似的目的，而不必创建容器"类.

I know this is reminiscent of Core Data, but that's not the point ;) I am just looking for a solution to implement something like that without having to create a "container" class.

预先感谢您的建议， 基督徒

Thanks in advance for your advices, Christian

推荐答案

为对象提供__unsafe_unretained属性，ARC将停止抱怨(但是请记住，它们没有保留！因此，您必须以某种方式存储一个强大的对象与他们的关系，如果你不想失去他们)

Give your objects the __unsafe_unretained attribute and ARC will stop complaining (but keep in mind that they aren't retained! So you have to somehow store a strong relationship to them, if you don't want to lose them)
